BELL DOOR-KNOB.

SPECIFICATION forming part of Letters Patent No. 590,192, datedSeptember 14:, 1897'.

Application filed y ,1897. Serial No. 685,133. (No model.)

To aZZ whom it may concern:

Be it known that we, EDWARD H. KINNA- MAN and BENJAMIN F. FLOUERS,citizens of the United States of America, residing at Fort Collins, inthe county of Larimer and State of Colorado, have invented certain newand useful Improvements in Bell Door-Knobs, of which the following isa'specification, reference being had therein to the accompanyingdrawings.

This invention relates to certain new and useful improvements indoor-bells, and more particularly to bell door-knobs.

The object of this invention is to provide a combination door-knob andbell which is exceedingly cheap and simple in its construction and onewhich can be easily secured to any of the doors and locks now in use.

With these objects in View our invention consists in the particularconstruction of the various parts and in the novel manner of combinationor arrangement of said parts, all of which will be described hereinafterand pointed out in the claim.

In the drawings forming a part of this specification, Figure 1 is a sideelevation of the knob, spindle, and bell and knob combined embodying ourimproved features. Fig. 2 is a central vertical section through thesame. Fig. 3 is a detail View of the clapper, mounted in the lowerportion of the bell.

Referring to the drawings, A represents a square hollow spindle having aslot B in one end thereof, and mounted in the said slot a.

ratchet 0, provided with a band a, which is clamped around the spindleand secured to the sides of the ratchet. This ratchet is onehalf thelength of the said slot and is adj ustably held therein by the saidband. If preferred, the ratchet and band may be made in one piece andadjustably secured therein in any manner desired. A spiral spring b,having one end secured in the recess 0 of the hollow spindle A and heother in the recess 01 of the ratchet O,serves to keep the said ratchetlocated in the lower end of the slot, and when the said spring iscontracted by forcing the ratchet to the upper end of the slot it ispartly secreted within the recess 0 and partly within the recess cl.

The end of the spindle nearest the slot is internally screw-threaded andprovided with a shoulder e for the support of the gong or ringingportion of the bell D,which is secured thereon by the screw f,whichpasses through the said bell and engages the internal screwthreads.Mounted upon the spindle below the slot is the lower portion ofthe bellE, having secured to its bottom a platform g, said platform having anaperture h, through which the spindle is passed. This platform is alsoat right angles to the said platform. sired, this platform might bedispensed with and the ears cast on the lower portion of the bell.Pivotally secured between these cars is a cam 'i, which is held inengagement with the ratchet O by the spring j, and secured to the upperportion or end and to one side of the said cam is an S-shaped wireZc,having secured to its loose end a clapper L. Secured to the other endof the spindle is a knob F, provided provided with oppositely-disposedears bent 7 If dewith an aperture rn, in which is secured thepress-button G, provided with a shoulder at on the inside of theknob,whicl1 prevents the said button from falling out. Connected to thispress-button is a rod H,extending through the hollow spindle and havinga washer 0 secured thereto, in order to give the said rod a centrallocation in the said spindle. The end of this rod is supported in therecess 19 'of the ratchet C.

By pressing the button the ratchet is made to traverse the slot in theshaft, thus throwing the cam into and out of engagement with the saidratchet and operating the clapper, which rings the bell repeatedly. Itwill thus be seen that we provide a bell door-knob which is compact,durable, and simple in its construction and will proficiently performall of its intended functions.

Having thus described our invention,what we claim as new, and desire tosecure by Letters Patent, is v In a bell door-knob the combination. of asquare hollow spindle having a slot in one end thereof and a ratchetmounted in and adapted to traversev the said slot, a spring engagingsaid ratchet, a platform secured in the lower portion of the bell, saidplatform havin g an aperture through which the said spindle passes andoppositely-disposed ears bent at right angles to-the said platform, acam pivotedly secured between the said ears, said cam supporting theclapper and held in engagement with the ratchet by a spring, a rodconnecting the said ratchet with a push-bu tton, substantially as shownand for the purpose set forth.

In testimony whereof we have affixed our signatures in presence of twowitnesses.
